- a technical problem commonly encountered in telecommunications systems is how to reduce or minimize both power consumption of terminals and unnecessary signaling in the network.
- the issues of power consumption and unnecessary signaling are often linked due to the fact that signal transmission typically accounts for a major part of the overall power consumption of a terminal.
- Reducing power consumption by terminals is particularly important in mobile telecommunications networks, due to the fact that mobile terminals are typically battery powered and thus have a finite power reserve. Excessive power consumption by mobile terminals can lead to unacceptably short intervals before the terminal battery needs to be recharged.
- Power consumption of mobile terminals can be a particular problem when the terminal is running one or more “always-on” applications.
- Always-on applications require the terminal to be constantly attached to a radio network and to be reachable over the current radio technology. Examples of always-on applications include push e-mail, instant messaging, and voice and video telephony.
- Embodiments of the present invention aim to address one or more of the above-mentioned problems.
- embodiments of the present invention aim to reduce power consumption and/or unnecessary signalling by terminals in a communications network.
- the present invention provides a method (e.g. for use in a telecommunications system).comprising monitoring a traffic pattern relating to a terminal, and regulating states (e.g. states of the Mobility Management protocol or of the Radio Ressource Control protocol) of the terminal according to the monitored traffic pattern.
- states e.g. states of the Mobility Management protocol or of the Radio Ressource Control protocol
- the present invention provides an apparatus (e.g. a network node in a communications system) configured to monitor a traffic pattern relating to a terminal, and regulate states of the terminal according to the monitored traffic pattern.
- an apparatus e.g. a network node in a communications system
- the present invention provides a communications system comprising a terminal and a network node, wherein the communications systems is configured to monitor a traffic pattern relating to a terminal, and regulate states of the terminal according to the monitored traffic pattern.
- the present invention provides a network element comprising monitoring means for monitoring a traffic pattern relating to a terminal and regulating means for regulating states of the terminal according to the monitored traffic pattern.
- the present invention provides a computer program product, comprising a set of instructions which when executed by a processor in a network node of a communications system, causes the network node to monitor a traffic pattern relating to a terminal, and regulate states of the terminal according to the monitored traffic pattern.
- the present invention provides a computer program comprising program code means adapted to perform any of the steps of a method as described above when the program is run on a processor.
- the present invention provides a computer program product comprising program code means stored in a computer readable medium, the program code means being adapted to perform any of the steps of a method as described above when the program is run on a processor.
- Embodiments of the present invention may advantageously reduce power consumption and/or unnecessary signalling of terminals by dynamically adapting states (e.g. Radio Resource Control or Mobility Management states) of a terminal according to the pattern of traffic to/from the terminal.
- states e.g. Radio Resource Control or Mobility Management states
- the traffic pattern may greatly affect the amount of time which a terminal spends in particular radio resource states, which in turn is highly determinative of the power consumption of the terminal.
- the time spent by the terminal in particular states can be regulated such that, for example, a power consumption increase due to an increase in particular types of traffic is minimized.
- embodiments of the present invention allow the configuration of states to be tailored to the activity and particular requirements of the terminal, and the power consumption of the terminal to be kept within acceptable limits. This can increase battery life of the terminal, especially in mobile terminals, as well as freeing radio and SGSN resources.
- the states are regulated through timers. After a defined period of time during which the terminal is inactive, e.g. during which the terminal does not transmit or receive any packet data, the timer expires. Typically the expiry of the timer causes the terminal to transition to a new state with a lower power. Setting of the timer involves defining a length of this period of inactivity before which the terminal shifts to a less power-consuming state.
- a terminal may have multiple states each having a different power consumption, and thus there may be multiple inactivity timers, each of which defines the length of an inactivity period before which the terminal shifts to a less power-consuming state.
- a length of the timer period i.e. the period of inactivity after which the terminal shifts to a less power-consuming state
- a length of the timer period is decreased. This is because if a terminal is sending a lot of traffic, such as frequent keep-alive messages, it would tend to spend more time in higher power-consuming states and its overall power consumption would increase. Decreasing the length of one or more timer periods in this situation minimizes the increase in power consumption by ensuring that the terminal returns to a lower power state more quickly after each transmission event (such as sending or receiving a keep alive message).
- a length of the timer setting is increased. This is because if the terminal is not sending a lot of traffic, its power consumption will be lower and it is acceptable for it to spend more time in higher power states.
- the traffic monitoring step of the present invention may involve detecting a pattern of transmission of messages to/from the terminal, wherein the messages serve to maintain a connection between the terminal and a further node in the communication system. More preferably the monitored traffic comprises keep alive messages transmitted to/from the terminal. In one embodiment the monitoring comprises detecting a frequency of transmission of messages such as keep alive messages relating to the terminal.
- the terminal is a mobile terminal
- the network is a mobile telecommunications network.
- the monitoring step typically results in a set of data, for instance in the form of a traffic profile, indicative of the traffic pattern associated with the terminal.
- the method preferably further comprises storing this data or profile in a node in the telecommunications system.
- the data may be stored in any suitable node in the network, for instance in a first controller node having a connection with the terminal.
- controller node is meant any node which performs control functions relating to a connection between the terminal and another node.
- the controller node may be a serving GPRS support node (SGSN) or radio network controller (RNC).
- the first controller node may be a node which also performs the monitoring step or may be a different node in the communication system.
- the method may further comprise transmitting the data to a second controller node, for instance when the terminal establishes a connection with the second controller node.
- the traffic pattern may be monitored by any suitable node in the communications network, for instance a controller node having a connection with the terminal.
- a controller node having a connection with the terminal.
- the node performing the monitoring step is an SGSN or RNC serving the terminal.
- the regulation of the states of the terminal may be performed by any suitable node in the telecommunications system.
- a controller node for instance the controller node which performs the traffic monitoring step
- attach accept and routing area accept messages the timer setting indication is added to a type of message which carries other data and would anyway be transmitted between the terminal and the node.
- the timer setting indication is provided in a message specifically transmitted for the purpose of modifying the timer.
- the method further comprises monitoring mobility of the terminal.
- the controller node may monitor the frequency of cell changes of the terminal. Mobility of the terminal may then be taken into account when regulating the states of the terminal, for instance when setting the inactivity timers, in addition to the traffic pattern (e.g. the frequency of keep-alive messages) associated with the terminal.
- the timer setting i.e. the length of the inactive period after which the terminal transitions to a lower power state
- the timer setting is preferably increased. This is because if the terminal is relatively static (i.e. its location is not changing), it will not be sending many cell update messages. Its power consumption will therefore be relatively low (compared to a terminal which is highly mobile) and an increasing the amount of time spent in a higher power state is acceptable.
- monitoring the traffic pattern of a terminal may include measuring a level of paging traffic associated with the terminal.
- a terminal In lower power states, a terminal may not be able to send or receive data without transitioning to a higher power state. In order for a terminal in a low power state to receive data, it is often necessary to page the terminal so that it can shift to a higher power state and receive the data.
- the amount of paging traffic may therefore be indicative of the amount of time which the terminal is spending in lower power states combined with the frequency with which it is sending/receiving keep alive messages.
- Decreasing the timer settings for terminals sending a lot of keep alive messages may increase the paging traffic, whereas increasing the timer settings for terminals sending fewer keep alive messages will tend to reduce paging traffic.
- Monitoring the level of paging traffic to a terminal and taking this into account (along with the keep alive frequency and optionally also the mobility of the terminal) when setting the timers can help to ensure that the paging channel does not become overloaded.
- the monitored traffic data for the terminal may additionally be used in setting the value of a periodic routing area update timer for the terminal.

- FIG. 1 illustrates schematically an example of a cellular network supporting packet-switched services in which the present invention may be implemented.
- the network 100 may be a 2G GPRS or a 3G GPRS network.
- the system 100 may be an EDGE/EGPRS network. Only some of the network elements of a 2G/3G network are illustrated in FIG. 1 .
- the radio access network comprises a number of base station systems.
- Each base station system comprises a base station controller (BSC) 4 and a number of base stations (BS) 5 , 6 .
- a terminal or mobile station (MS) 7 communicates with a base station 5 over a radio interface.
- the packet-switched core network of the system 100 comprises a number of GPRS Supporting Nodes (GSN).
- GSN GPRS Supporting Nodes
- Each mobile station registered for packet-switched services has a serving GSN, called SGSN, 3 which is responsible for controlling the packet-switched connections to and from the mobile station.
- the packet-switched core network is typically connected to further packet-switched networks via a Gateway GSN (GGSN) 2 . Services may be provided to the mobile station from an application server 1 connected to the GGSN 2 .
- GGSN Gateway GSN
- the MS 7 can be in a number of different states depending if it is transmitting data, or has transmitted data recently or not. The state has a significant impact on the power consumption of mobile terminals in the network.
- a terminal can be either in the state Ready (in which the MS is tracked at cell level) or the state Stand-by (MS tracked in Routing Area (RA) level, A routing area comprising many cells).
- the ready state cell updates are required each time the MS changes cell.
- the stand-by state The MS only needs to send updates when changing RA and the MS will be paged in the RA in case of a downlink packet.
- FIG. 2 illustrates the states in a 3G GPRS network.
- the terminal is in one of the following states:
- Timers T 1 , T 2 and T 3 are shown in FIG. 1 .
- the names T 1 , T 2 and T 3 are not officially used in 3GPP specifications but they have established in WCDMA parlance.
- the timers are network controlled and managed by the Radio Network Controller (RNC). The timers are discussed below:
- the inactivity timers T 1 and T 2 define the time after which the phone transitions from the more power-consuming states to less consuming states.
- the sum T 1 +T 2 defines the general power consumption behavior of the device, and the value of T 1 has a significant effect on the perceived performance of several applications.
- always-on applications require the terminal to be constantly attached to a radio network.
- many always-on applications require that frequent keep-alive messages are transmitted between the terminal and a server node in the network, for example between the mobile station 7 and the application server 1 shown in FIG. 1
- Transmission of a keep alive message moves the mobile station into, or maintains the MS in a high power state (e.g. Ready state in 2G, CELL_DCH or CELL_FACH in 3G).
- a high power state e.g. Ready state in 2G, CELL_DCH or CELL_FACH in 3G.
- Skype sends client originated keep-alive every 60 seconds.
- Nokia Email has a keep-alive sent by server every 4 minutes.
- a VPN client behind a NAT might send keep-alive every 30 seconds.
- the MS may be most of the time in an high power state (in 2G GPRS_Ready; in 3G PMM Connected DCH/FACH), as short data transmissions are sent/received only at regularly spaced intervals. This uses a lot of unnecessary battery power. In addition, it requires a lot of radio signalling (compared to the amount of data transferred) and thus consumes network resources. Transferring keep alive is not very cost efficient for operators.
- radio and mobility management timers are adapted dynamically depending on the pattern of traffic used.
- a node such as an SGSN or RNC controls timer setting by:
- the traffic characteristics (e.g. TCP keep-alive every 60 s, MS initiated) are stored in a new field “traffic profile” in the subscriber context (in SGSN or RNC), and transferred to a new node due to mobility events (such as inter SGSN RA update; SRNC relocation).
- FIG. 4 shows a flow diagram of how one embodiment of the present invention may be implemented in a GPRS network 100 as shown in FIG. 1 .
- an SGSN 3 sends attach accept and RA update accept messages to a mobile terminal 7 .
- These messages may include a ready timer and/or a periodic RA update timer, by which it is meant that the SGSN 3 indicates to the mobile terminal 7 in one or more such messages a setting for a length or period for these timers.
- the setting of the ready timer for example, defines the length of a period of time, after which the terminal shifts from the ready to the standby state, if the terminal is inactive during that period.
- the ready timer should be kept very short in order to reduce the amount of cell updates after a transmission.
- a value of 5 to 10 second should be appropriate.
- the drawback of this is that the amount of paging would increase.
- the operator could consider reducing the size of the RA to reduce paging load.
- a relative short value of the periodic Routing area update e.g. 30 minutes
- the periodic Routing area update should also be appropriate (Normally these MS will not perform periodic RA update due to frequent packet transmission. However, if they move out of coverage, the periodic RA update will expire and paging will be suspended. It will save paging capacity).
- such a setting would not be optimal for other users who are not having regular keep-alive message.
- the SGSN 3 initially (e.g. at attach) sends to the MS 7 a short Ready timer setting (5-10 seconds) and a short periodic RA Update timer (20-40 minutes). These timers are set to a value adapted for users having regular keep-alive.
- the SGSN 3 starts to monitor the traffic pattern, and at step 43 stores in the subscriber specific traffic profile information related to the usage of keep-alive.
- the mobile station 7 may be sending keep alive messages to the application server 1 in order to maintain a connection necessary for the server 1 to provide a service to the MS 7 .
- the SGSN 3 resets the timers to a different setting more appropriate for a terminal which is not sending regular keep-alive messages. For example, the Ready timer is set to 60 seconds and the periodic RA Update timer is set to 2 hours (see step 44 in FIG. 4 ).
- the SGSN 3 keeps monitoring the traffic pattern of this subscriber, as the user might activate a new application on his phone.
- the SGSN 3 again sets the timers appropriately based on the latest traffic pattern of the user. For instance, if activation of a new application leads to an increase in the frequency of keep alive messages, the SGSN may decrease the length of the timer setting (see step 45 ).
- the SGSN 3 may not be able to modify the timers. Using a small RA size will increase the probability that the user cross a RA border.
- the SGSN 3 may want to modify the timers, but may not receive RA updates. In that case, the SGSN 3 sends a message to the MS 7 to trigger a modification of the timers. This message may be sent according to a “timer modification procedure”, a dedicated message which can be used to reset the timers and generate a RA update.
- the SGSN 3 may take into account the load on a paging channel when setting the timers.
- the SGSN 3 may for example detect that a paging channel is overloaded and/or that certain MS 7 generate a lot of paging. Typically that could be the case if keep-alive is generated from the server, and the keep-alive intervals are short. In this case the SGSN 3 detaches the MS 7 , forcing it to re-attach and then sets a longer ready timer (reducing paging load at the expense of cell update load).
- the power consumption of the terminal may increase, in certain circumstances it may be necessary to avoid overloading on the paging channel.
- the method may be controlled by a traffic detection engine in, for example, an SGSN 3 or BSC/RNC 4 .
- FIG. 3 shows in more detail the SGSN 3 in which are represented certain features of one embodiment of the present invention.
- the SGSN 3 comprises a timer regulating/setting means 31 , which may comprise a transmission means for sending timer setting messages to the BSC/RNC 4 for forwarding to the MS 7 .
- the SGSN 3 also comprises a traffic monitoring means/traffic detection engine 32 which collects the relevant data relating to the MS 7 .
- the data may be stored in a traffic profile field along with other data relating to the subscriber of the MS 7 , in a storage means 34 also provided in the SGSN 3 .
- Processes performed by the SGSN 3 may be controlled by a suitably programmed processor means 33 .
- the traffic detection engine 32 is able to derive the number and/or frequency of keep-alive messages transmitted to/from the terminal 7 .
- Different applications running on a single MS may generate or require their own keep alive messages.
- each keep-alive application should have a profile containing the following information:
- the SGSN 3 also monitors the mobility of the user. For example, the SGSN 3 may monitor the frequency of cell changes. If the user has not changed cell for an extended period, e.g. at least 24 hours, the SGSN 3 may determine that the MS 7 is static and increase the ready timer value (the MS is not sending cell updates so it can stay in the ready state for longer).
- the timers are initially set based on traffic profile, but these settings can be modified or overruled based on mobility data of the terminal, e.g. if the MS 7 is static.
- the traffic profile is sent between nodes during inter SGSN Routing Area Update, Intersystem inter SGSN RA update, or SRNC relocation. This may be done because it takes time to determine a traffic pattern (to be accurate it might be worth waiting for 3 consecutive keep alive messages which can take 10-20 minutes).
- the new node can immediately set its timer accordingly.
- the method may also be implemented with timers in 3G networks.
- 3G networks such as UMTS and WCDMA
- key timers regulating Radio Resource Control states are controlled by the RNC.
- an RNC operates the same pattern detection mechanism and modifies the timers accordingly.
- the pattern detection is performed in a 3G SGSN, and the results or timers setting are sent to the RNC during RAB establishment or RAB modification. If the pattern changes (for instance if the user activates a new application), the SGSN detects this and sends a RAB modification to the RNC. The RNC then adjusts its timers.
- Embodiments of the present invention are applicable to all wireless packet technology, and so may also be applied to WiMAX or 3.9G (also referred to as 3G long-term evolution or 3G LTE) networks.
Abstract
Description
-
- CELL_DCH (Dedicated Channel). The MS is tracked at cell level. In this state, the current consumption is at its highest, comparable to the consumption during circuit-switched voice calls. The current consumption is around 220 mA or higher. The phone has a dedicated channel, which it does not share with other phones, so maximum throughput and minimum delay are achieved.
- CELL_FACH (Forward Access Channel). MS tracked at cell level. In this state, the phone shares the channel with other phones. This state is used when there is not much traffic to transmit. The battery consumption is roughly half of the consumption in the CELL_DCH state. The current consumption is roughly 120 mA.
- CELL_PCH (Paging Channel). MS tracked at cell level. This optional state offers the lowest current consumption of around 1-2 percent of the consumption in CELL_DCH state (around 4 mA). If there are downlink packets for the terminal, the terminal will be paged. In this state, the terminal is not able to send or receive packets, but the terminal will have to enter either the CELL_DCH or CELL_FACH state to send or receive. Not all network implementations currently use the CELL_PCH state.
- URA_PCH. MS tracked at UTRAN Registration Area (URA) level. If there are downlink packets for the terminal, the terminal will be paged in the URA. There are less updates but more paging than CELL_PCH. This state provides the same benefits as CELL_PCH and further enhances the battery performance when there is mobility.
- Idle mode. MS tracked at Routing Area level by the SGSN and there are no context in RNC. In this state, the phone does not have an RRC connection, so it is not possible to send or receive packets in this state. The terminal can still have a PDP context and it can be reached by paging procedures, after which the terminal can leave the idle mode and receive downlink packets. However an RRC connection will have to be established before the downlink packets can be received.
-
- T1 is an inactivity timer that is used in the CELL_DCH state. This timer is reset whenever there is traffic. The timer will expire only after an inactive period of T1, and the terminal will enter the CELL_FACH state. The shorter the T1 timer, the worse the user experience will be e.g. in web browsing. The T1 value may depend on the DCH data rate. The default values used in the Nokia RNC implementation are 5 seconds for 8-32 kbit/s, 3 seconds for 128 kbit/s, and 2 seconds for data rates greater than 128 kbit/s. In some networks, significantly longer timers than the Nokia defaults may be used.
- T2 is an inactivity timer in the CELL_FACH state. If CELL_PCH is used, the state machine will enter the CELL_PCH state after an inactivity period of T2. If CELL_PCH is not used, then the state machine will enter the idle state. The default value in Nokia's implementation is 2 seconds, but often significantly longer T2 values are used.
- T3 is a timer used in CELL_PCH (and in the URA_PCH state that may be introduced in the future). After staying in the CELL_PCH or URA_PCH for T3 seconds, the RRC connection will be released. This is typically a very long timer (several minutes or even tens of minutes).
